MACHINE FOR STAMPING RAILS.

SPECIFICATION forming part of Letters Patent No. 337,837, dated March 16,1886.

Application filed October 27, 1885. Serial No. 1RL051. (No model) To all whom it may concern.-

Be it known that we, HENRY G. KRIETE and WILLIAM GILLIEs, citizens of the United States of America, the former residing at Chicago and the latter at South Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Rail-Stamping Machines, of which the following is a specification, reference being bad therein to the accompanying drawings.

This invention has for its object to produce a machine by which rails can be stamped during the process of manufacture with successive numbers or other characters; and it consists of a machine stationed between the finishingrolls and sawing-machine of a rail-mill, which machine operates in the manner of a steamhammer, has stampingdies readily interchangeable during the operation, such stamping dies being automatically dropped upon the rail in advance of the striking-hammer, and being elevated again with such hammer high enough to clear the rail; also. of a vertically-movable anvil actuated by a treadle, to furnish at the proper moment the counterpoise to the blow upon the stamps, the wholev being arranged to be under easy control of the operator, all as hereinafter more fully described, and specifically claimed.

In the accompanying drawings, Figure 1 represents a side elevation of the machine; Fig. 2, an end elevation of the same; Fig. 3. a longitudinal vertical section of the steam-cylinder, and Fig. 4 a sectional end elevation of such cylinder and valve.

Corresponding letters in the several figures of the drawings designate like parts.

A denotes the standard frame, to be rigidly secured upon a suitable foundation. Against the upper curved end of this frame is bolted the steam-cylinder B, the bore of which, by suitable ports, communicates with the bore of the valve-chest O, that has steam inlet and exhaust port, in the usual manner.

The oscillating valve D, having stem d that projects through a stufiing-box, has secured upon its squared end a hand-lever, E, by which such valve is turned in one direction or the other for admitting steam from the boiler into either end of the cylinder.

F is the piston-rod and f the piston, which latter at the end of its upward stroke is cushioned by strikingagainst a pin, a, projected through the cylii'iderhead b, and having a collar shouldcring against the end of a spiral spring, 0, that is inserted into a cylindrical extension of head Z).

The lower cylinder-cover, g, is arranged with a stut'fingbox for forming a steam-tight packing around the piston-rod that passes through it. The flange of this cover 9 has extensions forming two eyes, h, that are diametrically opposite. The lower end of pistonrod F is inserted into a boss of the oblong hammer-head G, and is secured therein by a key. This hammer-head G has holes j in its ends,that coincide with the eyes h of cylindercover 9. A downwardly-projecting ridge of the hammer-head forms its striking-face.

The die-holder H is an oblong plate having five (more or less) square holes cut through its center line for the diesi to be inserted, and has holes in its ends, through which the shouldered ends of two rods, J, are inserted and secured by screw-nuts. These rods J are passed vertically through the holes in hammer-head G and eyes h of cylinder-cover g, to be guided therein. Collars K are adj ustably secured upon the guide-rods J, above hammer-head G, so as to have the die-holder sus pended thereon while such hammerhead ison its elevated position. The dies i are square bars of steel that fit easy into the holes of the holder H, and have each a head that receives the blow from the hammer, and prevents the dies from dropping through their holes in the holder. The lower end of each die is tempered after having cut its raised character.

L L are two of a series of guide or carrying rollers pivoted between stationary standards. Upon these rollers L L the rail travels from the finishing-rolls to the rail-saw, where it is cut proper length. and between two such rollers the machine is placed in a position that the web of the rail will move longitudinally in line with the row of diest'. Under the rail,

just vertically below the dies 2', is the anvil N, the die of which is shaped to pass between the head and flange of the rail, and to form a uniform supporting-surface for the web of the rail,

where the dies i will strike it from above. This anvil N, however, must notinterfere with the moving of the rails over the rollers L, and therefore such anvil is arranged to have a vertical motion on or between two guide-standards, p, and to be supported on one end of a lever, m, at the opposite end of which is formed a treadle, n. This lever m is pivotally supported at an intermediate point near the anvil in a rigid bracket, 0, and the anvil is nearly balanced by a counterweight, P, in a manner that, when released, the anvil N will be below and entirely clear of the rail, but that by stepping upon treadle n such anvil will be raised and pressed under the web of the rail.

Both the lever E for operating valveD and the treadle n are in convenient position to be gperated simultaneously by a single man or During the time the rail is held stationary to be sawed off the proper length, the operator puts hisfoot upon treadle n, to press the anvil under the web of the rail, and then, by swinging the lever E upward, he turns the valve D to admit steam into the cylinder above the piston, when such piston is forced downwardwith great velocity. The dies i will now land upon the rail first, and then the die-holder will find its resting-place onsuch rail,whereby the dies are pushed upward in such die-holder, but held securely in proper position on the rail, while the hammer-head G, now following, will strike a heavyblow upon such dies, which blow is counterpoised by the anvil N.

- As soon as the blow has been struck, the operator releases treadle n, and swings the lever E downward, turning the valve to admitsteam under the piston, when the hammer-head is lifted on its upward course, also elevating the dies to clear the rail, which now is forwarded to the cooling-bed. During the interval for stamping the next rail the operator has time to exchange or interchange the dies i, suffieient space being provided between the die-holder H and hammer-head G for removing and inserting dies while such hammerhead is on its elevated position.

What we claim is 1. In a machine substantially as described,

the combination, with the cylinderand pistonrod carrying the hammer-head, of a die-holder guided by and suspended from such hammerhead, being automatically elevated thereby to clear the rail and provide sufficient space for exchanging dies, as and for the purpose set forth.

2. In a machine substantially as described, the combination, with the cylinder, piston-rod, and hammer-head, of a dieholder having square holes for the reception of headed dies,- and being guided by and suspended from such hammer-head, to be automatically elevated for clearing the rail and for providing suflicient space for exchanging dies, as and for the purpose set forth.

3. In a machine substantially as described,.

able collars for holding suspended such dieholder and hammer-head while on its elevated position, as and for the purpose set forth- 4. The combination,with cylinder B, having guide-eyes h, and the piston-rod F, carrying hammer-head G with guide-holes j, of dieholder H, having guide-rods J with collarsK, all constructed and arranged substantially as described, for the purpose specified.

5. The combination, with cylinder B, pistonrod F, hammer G, and die-holder H, and with rollers L, of the vertically-movable anvil N, actuated by treadle n, all substantially as described, for the purpose specified.
